Purpose: The Affordable Care Act (ACA) required that private insurance plans allow clinical trial participation and cover standard-of-care costs, but the impact of this provision has not been well-characterized. We assessed rates of insurance clearance for trial participation within our large early-phase clinical trials program, before and after implementation of the requirement.Experimental Design: We analyzed the departmental database for the Clinical Center for Targeted Therapy (CCTT) at MD Anderson Cancer Center (Houston, TX)...

BACKGROUND: Biologic factors guide treatment decisions and have a significant impact on prognosis for breast cancer patients. This study was undertaken to develop a staging system incorporating biologic factors in addition to standard anatomic factors in the American Joint Committee on Cancer (AJCC) pathologic stage (PS) to assess disease-specific survival (DSS). METHODS: Overall, 3327 patients treated with surgery as an initial intervention at MD Anderson Cancer Center from 2007 to 2013 were identified...

The standard approach of performing a completion axillary lymph node dissection (cALND) after a positive sentinel node for breast cancer patients is no longer generally accepted. This study applied the criterion of a 27% risk of having residual positive lymph nodes calculated by the MD Anderson nomogram to perform a cALND. This 27% cut-off is based on the number of positive non-sentinels in the Z0011 trial. A cohort of 166 cN0, sentinel positive breast cancer patients was used to validate the MD Anderson nomogram...

BACKGROUND CONTEXT: Neoplastic spinal instability is movement-related pain or neurologic compromise under physiologic loads with the Spinal Instability Neoplastic Score (SINS) developed to facilitate diagnosis. There is a paucity of evidence that mechanical instability correlates with patient-reported symptoms and that surgical stabilization significantly improves these patient-reported outcomes (PRO). PURPOSE: The objective of this study was to determine if SINS correlates with patient-reported preoperative pain and disability and if surgical stabilization significantly improves PRO...

The NADPH oxidases (NOXs) play a recognized role in the development and progression of inflammation-associated disorders, as well as cancer. To date, several NOX inhibitors have been developed, through either high throughput screening or targeted disruption of NOX interaction partners, although only a few have reached clinical trials. To improve the efficacy and bioavailability of the iodonium class NOX inhibitor diphenylene iodonium (DPI), we synthesized 36 analogs of DPI, focusing on improved solubility and functionalization...

Treatment response and survival after bevacizumab failure remains poor in patients with glioblastoma. Several recent publications examining glioblastoma patients treated with bevacizumab have described specific radiographic patterns of disease progression as correlating with outcome. This study aims to scrutinize these previously reported radiographic prognostic models in an independent data set to inspect their reproducibility and potential for clinical utility. Sixty four patients treated at MD Anderson matched predetermined inclusion criteria...

Importance: We previously demonstrated that a major pathologic response to preoperative therapy, defined histopathologically by the presence of less than 5% viable cancer cells in the surgical specimen, is an important prognostic factor for patients with pancreatic ductal adenocarcinoma. However, to our knowledge, the patients most likely to experience a significant response to therapy are undefined. Objective: To identify clinical factors associated with major pathologic response in a large cohort of patients who underwent preoperative therapy and pancreatectomy for pancreatic ductal adenocarcinoma...

Invasive fungal infection (IFI) is a leading cause of morbidity and mortality in immunocompromised cancer patients. New triazole-based antifungal agents have been recommended for IFI prophylaxis in these patients. This retrospective study compared the safety and efficacy of voriconazole and posaconazole as prophylaxis in patients with hematological malignancies (HM), who were admitted to The University of Texas MD Anderson Cancer Center between January 2014 and August 2015, and who were started on single antifungal prophylaxis consisting of either voriconazole or posaconazole...

BACKGROUND: Hepatocellular carcinoma (HCC) prognosis depends on clinicopathological features in addition to the treatment provided. We aimed to assess the natural history of TNM stage I HCC tumors which received different treatment over a period of 20 years. METHODS: Between 1992 and 2011, a total of 397 stage I HCC patients were included. Detailed information was retrieved from MD Anderson Cancer Center patients' medical records. The Kaplan-Meier method was used to calculate patients' overall survival (OS)...

OBJECTIVE: Chronic myeloid leukemia treatment monitoring using polymerase chain reaction-based peripheral blood testing of t9;22 BCR-ABL1 provides improved test sensitivity over cytology but suffers from inadequate standardization in most laboratories due to variations inherent in the existing polymerase chain reaction methodologies. We performed the initial analytic performance evaluation of a novel competitive template-based peripheral blood b2a2/b3a2 transcript abundance method, called standardized nucleic acid quantification (SNAQ) test, with hypothesis that this will produced more consistent results with less frequent interlaboratory variations...

Md Anik Alam, James Drennen, Carl Anderson
Designing a calibration set is the first step in developing a multivariate spectroscopic calibration method for quantitative analysis of pharmaceutical tablets. This step is critical because successful model development depends on the suitability of the calibration data. For spectroscopic-based methods, traditional concentration based techniques for designing calibration sets are prone to have redundant information while simultaneously lacking necessary information for a successful calibration model. A method for designing a calibration set in spectral space was developed...

PURPOSE: Lynch syndrome (LS) is a hereditary condition that increases one's risk of developing colorectal, endometrial, and other extracolonic cancers. MD Anderson Cancer Center at Cooper implemented a reflex screening protocol for DNA mismatch repair (dMMR) deficiency. Those with findings suspicious for LS were referred for genetic counseling (GC). Our goal was to assess compliance with GC and factors associated with successful follow-up. METHODS: Immunohistochemistry (IHC) for the MMR proteins MSH2, MLH1, MSH6, and PMS2 was performed on all colorectal tumor resections from patients ≤70 years old and all stage II cancers...

Cancer is a disease with abnormally proliferating cells and therefore proliferation rate is an important index for assessing tumour growth. Ki-67 is a commonly used proliferation marker considered to be an unfavourable prognostic marker in some tumors, while Thymidine kinase 1 (TK1) is an interesting proliferation marker because its levels are highly dependent on the growth stage of cells. To define the immunohistochemistry (IHC) expression of the TK1 in patients with ovarian serous adenocarcinoma and establish its potential role as a new biomarker for progressive disease, we analyzed the expression patterns of TK1 and Ki-67 in 109 patients with ovarian serous adenocarcinoma...

Muscle cells are a syncytium in which the many nuclei are positioned to maximize the distance between adjacent nuclei. Although mispositioned nuclei are correlated with many muscle disorders, it is not known whether this common phenotype is the result of a common mechanism. To answer this question, the expression of genes linked to Emery-Dreifuss Muscular Dystrophy (EDMD) and Centronuclear myopathy (CNM) was disrupted in Drosophila, and the position of the nuclei was evaluated. We found that the genes linked to EDMD and CNM were each necessary to properly position nuclei...

BACKGROUND: The important but complicated research questions regarding the optimization of mammography screening for the detection of breast cancer are unable to be answered through any single trial or a simple meta-analysis of related trials. The Cancer Intervention and Surveillance Network (CISNET) breast groups provide answers using complex statistical models to simulate population dynamics. Among them, the MD Anderson Cancer Center (Model M) takes a unique approach by not making any assumptions on the natural history of breast cancer, such as the distribution of the indolent time before detection, but simulating only the observable part of a woman's disease and life...

BACKGROUND: Obesity is an established risk factor for renal cell carcinoma (RCC). Although genome-wide association studies (GWAS) of RCC have identified several susceptibility loci, additional variants might be missed due to the highly conservative selection. METHODS: We conducted a multiphase study utilizing three independent genome-wide scans at MD Anderson Cancer Center (MDA RCC GWAS and MDA RCC OncoArray) and National Cancer Institute (NCI RCC GWAS), which consisted of a total of 3,530 cases and 5,714 controls, to investigate genetic variations in obesity-related genes and RCC risk...

BACKGROUND: Cancer patients' symptom burden is commonly attributed to their cancer and treatment. Increasingly, cancer patients have many other chronic comorbid conditions. However, the degree to which these comorbid conditions may contribute to the patient-reported symptom burden is unclear. METHODS: This study explored the relations between the presence of comorbid conditions, the symptom experience and burden, and the perceived bother from cancer or comorbid conditions in 3106 cancer patients...

PURPOSE: The survival duration of elderly patients with epithelial ovarian carcinoma is shorter than that of their younger counterparts. This variation in survival duration is likely attributed to differences in the distribution of histological type or grade, International Federation of Gynecology and Obstetrics (FIGO) staging, and undertreatment, but this observation remains controversial. This study aimed to investigate the biological factors other than selection bias associated with the decreased survival of elderly patients with ovarian carcinoma...

We report the first measurement of the elliptic anisotropy (v_{2}) of the charm meson D^{0} at midrapidity (|y|<1) in Au+Au collisions at sqrt[s_{NN}]=200  GeV. The measurement was conducted by the STAR experiment at RHIC utilizing a new high-resolution silicon tracker. The measured D^{0} v_{2} in 0%-80% centrality Au+Au collisions can be described by a viscous hydrodynamic calculation for a transverse momentum (p_{T}) of less than 4  GeV/c. The D^{0} v_{2} as a function of transverse kinetic energy (m_{T}-m_{0}, where m_{T}=sqrt[p_{T}^{2}+m_{0}^{2}]) is consistent with that of light mesons in 10%-40% centrality Au+Au collisions...
